Please help me find this motion Focus Light/Cloud/Particle background effect!

How do I get the effect shown in the background of this interview (Link below). The motion particles shining light on parts of the illustration making one focus on certain parts more then others, is it simply particles or is this a cloud? Would I find this effect easily if so what is it called?

Thank you!!

look for "fractal noise" for the logo, as for the other particles - look for "particles on black" stock footage. or try to create these yourself with "particular"
